how many hours can the energizer run for?

It depends on the load but you will begin to hear the fan cut on when it starts to pull a certain load, and then it will beep if the load is to much on the device. There is a breaker on it so it will shutoff if the load is too much. But when kept at relatively normal levels it can run all day.

With a high quality battery (Energizer, Duracell, etc.) it's about 10 hours. With a "99-cent store" battery it's about 4-5 hours max. Don't forget re-chargeables - that's the key - carry a couple with you; they're very little.

Usually 4-6 hours is enough, but if it is run down completely you might want to leave it on for up to 8 hours. If you have a volt meter with a 6 volt option, you can check it that way.

for basic use I would say it can run for at least 4 hours or more, obviously less if youre gaming and such.

If you are asking how long a fully charged battery last until it runs out power I'd say about 4 hours running a PC with few applications. It is worth the money I pay for it.

Mine has stayed on and functioning for over six hours. Have yet to run it down.

5-8 hours depending on what you are doing and depending on what battery mode you have it in. There is power saver, balance, and high performance options

It hard to say but I leave mine on charge the day prior to using for a period of time. I can get about 7hrs playtime.

It depends upon the load being drawn by what you have plugged into it. The APC Smart UPS brochure shows the run time depending upon the wattage. For example if you are drawing 200 watts of power, then with a fully charged battery it should last about 20-22 minutes according to the brochure.

Personally, I've only run the unit for 24 hours straight. I cannot comment on 'several days' but I believe that it should also be fine. Also, you should note that the settings can be configured for it to turn itself on and off AUTOMATICALLY. This means that, there is no need for the unit to run CONTINUOUSLY, for several days.

I tend to keep mine on power save, it seems to last pretty well. I'm not sure and exact answer on a number but several hours.

I have used mine for at least 4 hours. After 6 or 7 years it still lasts over 2 hours.

Depends on the volume you want to achieve, and how long you plan to run it. I would say it would work fine for a couple hours at 70-80% power.

The short answer is "Yes". David Tullos says it will last 8 - 10 hours on full load (1500 watts) but I do not believe it will last any where near that long. The first link I have provided below computes the battery will last .66 hours at a continuous 1500 watt load and that makes sense to me. I have run a 2500 watt inverter on 1 of these 12 volt 100 amp hour batteries. The inverter must be a 12 volt inverter. The question is...how long will the battery last. That depends on the average (a refrigerator for example) or continuous wattage (maybe a 1500 watt heater running continuously) used by the electrical devices being powered. Of course the fridge doesn't run continuously so you have to take that into account. If you run a 1500 watt heater continuously off of this 100 amp hour battery you should be able to compute how long it will last. You also do not want to discharge the battery too much below 50%. There is a certain amount of research you need to do part of which involves using very thick gauge (probably at least 4 awg but maybe as large as 0 awg) cables from the inverter to the battery which your inverter documentation should tell you. The general rule of thumb for DC current is that for every 1 amp of AC current used by an appliance you will draw 10 amps of DC current from the battery. 10 amps of AC current will draw about 100 amps of DC current. Here are some links that might help. I do not know how reliable these are but they seem to be correct with my understanding of electricity and the research I've done. The first link seems to be the simplest to use by plugging in your own data. http://usasolarwind.com/Tools/BET.html http://powerstuff.co.za/battery-size-calculator/ http://www.bdbatteries.com/dcdcsolar.php I hope this helps.

I concur w/abt 6 hours. My son runs this thing w/o charging for a few days @ a time.

In power saver mode, can use for 4 to 5 hours, less in high performance mode.

I have mine plugged into a power strip. I run a vibratory tumbler with mine. I can set the run time and forget it. You can set it for 1, 2 4 or 8 hours. I really like mine. It is simple and easy to use.
